• 2nd Class Lever

• 3rd Class Lever

Which lever system is this?

• 3rd Class Lever

• 2nd Class Lever

• 1st Class Lever

Which lever system is this?

• 2nd Class Lever

• 3rd Class Lever

• 1st Class Lever

What is the formula to get force?

• f=ma

• f=m-a

• f=m/a

What force can do?

(a)  

Which part of a lever is in the middle in a second class lever?

• Fulcrum
• Resistance
• Effort
• Effort arm

For a first class level, the fulcrum is placed

• Between the effort/force and resistance/weight

• Effort/force in the middle with fulcrum on one end and resistance/weight on the other

• Resistance/weight in the middle with fulcrum and effort/force on the ends

How many classes of levers are there?

• 1

• 2

• 3

• 4

Force is a push or pull on an object to create movement.

• True

• False
